Not very much related here - or maybe it is: I tried my Poulan 25 on 50-50 mixture (gas methanol). This time the engine had magneto ignition. I couldn't start it by hand, but field started did as usually great job. I got maximum 7500 rpm on MA 16x8 Classic (the same load as APC 17x6), however the lowest stable idle was around 2000 rpm. basically it is the same result as with glow plug (but glow idle better).

I just got another Poulan 25cc to play with. Is any way to get a better power from it? Some hacking, sawing, drilling etc? Maybe bigger carb? I wonder if is any way I can get close to MVVS 1.6 what means 18x6W at 8200 rpm.
